LAKE CITY, 4UTAH TERRITORY.

GRAIN-WINNO'WER.'

SPECIFICATION forming part of Letters Patent No, 357,525, dated February 8, 1887.

Application tiled July 6, 1886. Serial No. 207,242. (No model.)

.To all whom it` may concern:

Be it known that I, CHARLES '.I. ERIcsoN, a citizen of the United States, residing at Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented certain new and useful Improvements in Grain-Winnowers; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled iu the art to which it appertains to make and use the same, reference being had'to the accompanying drawings, and to the letters and gures of reference marked thereon, which form a part of this specification.

This invention has reference to that class of devices known as grain-winnowers, and it consists in a light, portable, and conveniently-constructed winnower or blower, which is particularlyT adapted to be used in cleaning oats or other grain to be fed to race-horses at the stable or on the track, and it further comprises certain peculiarities in the construction and arrangement of parts, as will be hereinafter fully described, and then specifically pointed out in the claims.

In the annexed drawings, illustrating my invention, Figure 1 is a side 'elevation of my improved grain-winnower. Fig. 2 is an elevation of the opposite side of the winnower, and Fig. 3 is a vertical section through the device.

Similar letters denote corresponding parts throughout the several views.

The frame of the winnower is small and compact, so as to be easily portable.

A represents a hopper, into which thegrain to be winnowed or cleaned is fed. The lower end of this hopper is open, and through it the grain falls upon an inclined vibrating screen, D. Y The chaff, dirt, and line particles of refuseare blown from the screen D by an airblast coming through a channel, h, from a blast-chamber, B, while the grain which is thus cleaned is directed by the inclination of the screen downward into aL lower receiving-chamber, C, whence it can be removed through any suitable opening-as, for instance, the opening shown in Fig. l--which is closed by a vertically-sliding gate.

Vithin the hopper A, near its lower opening, is journaled a transverse shaft, g, which is preferably provided with wings or strips, as shown, in order to regulate the descent of the grain through the hopper. Upon one end of this shaft, .which extends through the casing of the device, is secured a handwheel, E, having handle a. Within the blastchamber B is situated arot-ary fan, of any suitable construction, mounted upon a shaft, c, one ofwhose externally-projecting ends is provided with a pulley, F, which connects by a belt, b, with the wheel E, and is operated thereby. Thus it will be se'en that as the hand-wheel E is rotated the grain will be caused to descend through-the bottom of the hopper by means of the wings or strips on shaft g, and at the same time a powerful blast of airwill be generated Within the blastchamber and caused to pass by the channel h through the descending grain and drive the chaff out over the screen.

The screen D is a vibratory screen, being made in order to shake the grain off into the chamber below. It is vibrated bymeans of a connection with the fan-shaft. One of the ends of said shaft is provided with an eccentric, G, whose periphery is preferably grooved. A horizontal rod, d, rests upon said grooved eccentric, being held down thereon by means of a spring, e, affixed to the outside of the casing. (See Fig. 2.) Said rod d, at the end away from the eccentric, isbent to a right angle and passed through the casing and beneath the screen at f. The screen being'pivoted Vat j, and held loosely within grooves i in the casing,.it is evident that at each revolution of the eccentric the rod d will be raised and lowered, and that the interior `end of said rod will be actuated to vibrate the screen.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A grain-winnower comprising the hopper A, blast-chamber B, the rotary fan, the blast-channel 7L, inclined screen D, shaft g, provided with wings or strips, the handwheel E, shaft c, having pulley F and eccentric G, Ithe belt b, rod el, and spring e, all arranged substantially as shown and described.

2. A granWnnOWer comprising the 110pper A, the blast-chamber B, the fan, the shaft c, provided with pulley F :md eccentric G, the vibratory inclined screen D, pivoted to the sides of the easing, the rod (l, having inturned end f, and the spring c, substantially as described.

In testimony whereof I aflx my signature in 1C. presence of two Witnesses.

CHARLES J. ERICSON.
